Boca Damas • Surf Spot Statistics

Best Surf Season (April - September)

Boca Damas is, first and foremost, a south-southwest swell magnet. During the northern-hemisphere spring and summer, the southern-hemisphere winter storm track becomes active across the South Pacific, and the resulting long-period SSW and SW groundswells travel thousands of miles into this SSW-facing corner of Costa Rica. Average wave heights climb to 1.2-1.4m (4-4.6ft) from April onward, with a healthy share of 5-6.5ft (1.5-2m) pulses between May and August. Periods sit in the powerful 13-14s range, so the beach sees steep, organized lines rather than wind chop. The Intertropical Convergence Zone drifts north during these months, increasing humidity, rainfall and cloud, and onshore S/SW flow often rules the afternoon. Still, early-morning offshore windows from N, NNE, NE and NNW offer the cleanest and arguably best surf of the year.

Fair Surf Season (March and October - November)

These are transition months, when the swell and wind are caught between dry-season and wet-season patterns. March benefits from dry, light N/NNE offshore flow and a building SSW swell, but the size has not yet reached full strength. October and November still hold decent 1.2-1.4m (4-4.6ft) SSW/SW swells, but periods ease to 12-13s and onshore winds become more persistent, making the surf less consistent and harder to time. Rain is also more frequent in this period, especially in October.

Low Surf Season (December - February)

The smallest waves of the year arrive with the northern-hemisphere winter, when South Pacific low-pressure activity shifts or weakens and average swell heights drop to 0.9-1.1m (3-3.5ft). However, this is also the heart of the Central American dry season, and northerly surges - often associated with strong North American high pressure - blow offshore across the beach. The result is cleaner, more user-friendly surf: small but fun-sized, with light winds, less rain, and warm water. It is the low season in size, but not in quality.
